Abstract
Official abstract text for this publication.
Provided is a binder composition for electrodes that has high stability in the form of a liquid composition dissolved or dispersed in a solvent and can improve cycle property of a non-aqueous electrolyte battery. The binder composition used is a binder composition including a polymer A containing 80% by weight or more and 99.9% by weight or less of a repeating unit derived from a monomer including a nitrile group and 0.1% by weight or more and 20% by weight or less of a repeating unit derived from an ethylenically unsaturated compound, wherein a weight-average molecular weight of the polymer A is 500,000 to 2,000,000, and a molecular weight distribution (Mw/Mn) of the polymer A is 13 or smaller.
First claim
Opening claim text (preview).
The invention claimed is: 1. A binder composition for a positive electrode of a non-aqueous electrolyte battery, the binder composition comprising a polymer A containing 80% by weight or more and 99.9% by weight or less of a repeating unit derived from a monomer including a nitrile group and 0.1% by weight or more and 20% by weight or less of a repeating unit derived from a methacrylic acid, wherein a weight-average molecular weight of the polymer A is 500,000 to 2,000,000, and…
